Case Study: Mitsubishi Electric achieves faster development and higher software quality with Synopsys Coverity Static Analysis

Mitsubishi Electric Adopts Development Testing to Enhance Customer Satisfaction

Mitsubishi Electric’s Sanda Works, a pioneer in car navigation systems, faced rapidly growing software complexity and tighter delivery schedules as navigation systems became feature-rich and pre-installed across more vehicle models. Strict automotive quality and safety requirements made early defect detection essential, but previous static analysis tools produced high false-positive rates that wasted engineers’ time and threatened development velocity.

Sanda Works adopted Coverity Static Analysis and the Coverity Integrity Manager to front-load testing and track defects. The solution’s high accuracy and clear root-cause reporting reduced false positives, streamlined triage and reporting, and improved the share of bugs fixed during coding by about 5–10%, enabling better planning, faster development cycles, broader team adoption, and higher overall product quality and customer satisfaction.
